A Food and Drug Administration review suggests menthol cigarettes likely pose a greater public health risk than regular cigarettes but does not make a recommendation on whether to limit or ban the minty smokes.

Menthol is a flavor additive widely used in consumer and medicinal products; however, its use in tobacco products is not currently regulated.

The federal agency released the independent review on Tuesday and is seeking input from the health community, the tobacco industry and others on possible restrictions on the mint-flavored cigarettes.

The FDA evaluation concluded that there is little evidence to suggest that menthol cigarettes are more or less toxic or contribute to more disease risk to smokers than regular cigarettes. However, there is adequate data to suggest that menthol use is likely associated with increased smoking initiation by younger people and that menthol smokers have a harder time quitting, the review said.

There’s also evidence indicating that menthol’s cooling properties can reduce the harshness of cigarette smoke and that menthol cigarettes are marketed as a smoother alternative, the review said.

“Menthol cigarettes raise critical public health questions,” Mitch Zeller, director of the Center for Tobacco Products, said in a conference call with reporters.

Zeller said there’s “no holdup” on the FDA proposing restrictions on menthol but that there are still “some important questions” that need to be answered. The agency is commissioning further research.
